Hi Jason,
Just to double check...
1) Are you using the driver AND cuda version that go together?
E.g. if you installed the Release candidate driver you should use the
release candidate compiler. If you are using the beta compiler from the
website you should use the beta compiler from the same page.
2) Did you reboot after changing the graphics driver?
3) Are you certain you are using the same binary model in all cases? E.g. an
x86_64 OS + x86_64 version of gfortran and gcc + x86_64 versions of the cuda
driver and compiler?
4) Are you using the default precision model?
Specifying -cuda_DPDP or -cuda_SPSP could have 'undefined' results right
now.
All the best
Ross
